Hello!

I am having an issue with the OrgMassSpecR package.  I run my HPLC using a
DAD detector.  My raw data is exported form chemstation as a csv file.  I
then upload the csv into Rstudio no problem.  Using the DrawChromatogram
function, I get a nice chromatogram, and my retention time, peak area, and
apex intensity values are given as well.

The problem comes with the peak area value given. The peak area is much
smaller than a value that would make sense.  My peak area value is actually
less than my apex intensity value.  Is this because I am using a DAD
detector rather than an MS? If so, is there a simply way to edit the peak
area equation so that it will also work with absorbance values?

Any help is greatly appreciated.

Thanks for your time.
